To find:

• Let's use the Direct Rule of Three

1. Distance in miles       2.  Time in minutes

0.875                      15

             x                           60

• -----------------------------------------------------------------------------

• 15x = 0.875 * 60
• 15x = 52.5
• x = 52.5/15
• x = 3.5
• -----------------------------------------------------------------------------

Answer: 3.5

Answer 2

Answer: Lien walked 3.5 miles per hour of speed.

Step-by-step explanation:

Distance Lien walked = 7/8 of a mile = 0.875 miles

Distance in miles     Time in minutes

          0.875                      15

             x                           60

Calculations:

15x = 0.875 * 60

15x = 52.5

x = 52.5/15

x = 3.5
